to provide a construction anc which w ll permit the free The drawingrepresents a perspective view of the device, similar parts of which areindicated by corresponding characters of reference.

Referring by letter to the drawing, a a represent two parallel tubesconnected at opposite ends by transverse tie-wires a a, which extendinto the tube and are brazed or soldered, thus forming a rectangularframe or base. There are also projected into the ends of the tubes andsecured therein by brazing or soldering the ends of two inverted-U-shaped members I) b. Each of the invertedis formed of resilient orspringwlre, and ad acent to the ends of the respective tubes a a each isformed with spring-coils 6 The tendency of the inverted-U-shaped membersI) b spring-coils b is to straighten into a plane coincident with thatof the rectangular frame formed by tubes at a and transverse wires (1 a.

In the respective legs of the inverted- U-shaped member I), at directlyopposite points, are formed bights 6 which constitute the bearings forthe revoluble member 6 The revoluble member 6 against further rotationby 7 of the extremity b of the crank I) with the leg of theinverted-U-shaped member Z). The various parts being of resilientmaterial will spring aside sufficiently to allow the crank I) to passwhile the strip is being wound upon the revoluble member 6 It is obviousthat by the use of the same construction, but differently proportioned,being constructed on a largerscale of proportionately stronger parts,the devlce may be Havmg thus described my invention, I claim 1. As anarticle of manufacture, a device verted-U-shaped members attached tosaid rectangular frame, having a tendency to move into the plane of saidrectangular frame,

earings formed on one of said inverted-U- shaped members, a revolublemember having member, means for securing said member in its adjustedposition and a strip of fabric connected to one of said U-shaped membersand extending over the other of said members and engaging with saidrevoluble member, substantially as specified.

2. As an article of manufacture, a device comprising two parallel tubes,transverse 1s provided with a longitudinal slot 6 for the purposehereinafter mentioned.

In the drawing the revoluble member I) is shown as constructed of twoparallel wires, one of which is extended, as at Z), to form a crank, theextremity of which is turned inward in a hook, as at b, to engage theleg of comprising a rectangular frame, resilient inwires connecting saidtubes, and forming a rectangular frame, inverted-U-shaped members,formed of resilient wire, spring-coils formed in said U-shaped members,said mem- 5 bers being connected to the opposite ends of the respectiveaforementioned tubes, bights formed in one of said U-shaped members atdirectly opposite points on the legs of said member, a revoluble memberfor-med of two 10 parallel wires, sa1d wires being coherent at pointsadjacent to their extremities mounted in said bights, the projecting endof one of said parallel wires being formed; into a crank and adapted toengage with the legof said U- shaped member above or below said bight,15 substantially as specified.

In testimony whereof I have hereunto set my hand this 27th day ofFebruary, A. D. 1906.
